Application of a Genetic Algorithm for the Optimization of a Complex Reservoir System in Tunisia

Louati, Mohamed; Benabdallah, Sihem; Lebdi, Fethi; … - In: Water Resources Management 25 (2011) 10, pp. 2387-2404

A genetic algorithm (GA) model is developed and used for optimizing the allocation of water resources within a complex multiple reservoir system located in Tunisia. The GA model considers two objectives: the water allocation to demand centers and the salinity level of the water supply to end...

Overall design optimization of wind farms

González, J. Serrano; Rodríguez, Á.G. González; … - In: Renewable Energy 36 (2011) 7, pp. 1973-1982

An Evolutive Algorithm (EA) for wind farm optimal overall design is presented. The algorithm objective is to optimize the profits given an investment on a wind farm. Net Present Value (NPV) will be used as a figure of the revenue in the proposed method. To estimate the NPV is necessary to...

Identifying the Pareto-front approximation for negotiations of BOT contracts with a multi-objective genetic algorithm

Liou, Fen-may; Yang, Chien-hui; Chen, Boarliang; Chen, … - In: Construction Management and Economics 29 (2011) 5, pp. 535-548

The build-operate-transfer (BOT) project is formulated based upon cooperative partnerships among various public and private parties. Win-win negotiation solutions are especially essential for parties that usually have conflicts of interests. A simulation-based multi-objective genetic algorithm...

Retail Channel Structure Impact on Strategic Engineering Product Design

Williams, Nathan; Kannan, P. K.; Azarm, Shapour - In: Management Science 57 (2011) 5, pp. 897-914

We examine, in a strategic setting, the broad issue of how retail channel structures--retail monopoly versus retail duopoly--impact a manufacturer's optimal new product design, both in terms of engineering design specifications as well as manufacturer and retailer profits. Our strategic...

Efficient and accurate quadratic approximation methods for pricing Asian strike options

Chang, Chuang-Chang; Tsao, Chueh-Yung - In: Quantitative Finance 11 (2011) 5, pp. 729-748

This study is on valuing Asian strike options and presents efficient and accurate quadratic approximation methods that work extremely well, both with regard to the volatility of a wide range of underlying assets, and longer average time windows. We demonstrate that most of the well-known...

Optimal hedge fund portfolios under liquidation risk

Brandon, R. Gibson; Gyger, S. - In: Quantitative Finance 11 (2011) 1, pp. 53-67

We use an expected utility framework to integrate the liquidation risk of hedge funds into portfolio allocation problems. The introduction of realistic investment constraints complicates the determination of the optimal solution, which is solved using a genetic algorithm that mimics the...

Effectiveness of Heuristic Based Approach on the Performance of Indexing and Clustering of High Dimensional Data

Chen, Alan; Gao, Shang; Jarada, Tamer N.; Zhang, Ming; … - In: Journal of Information & Knowledge Management (JIKM) 10 (2011) 03, pp. 261-271

technique applicable to indexing and clustering algorithms which need to calculate distances and check them against some minimum … algorithms. Runtime for all three algorithms with this optimisation scenario was reduced, and the clusters they returned were … verified to remain the same as the original algorithms. The optimisation technique also shows potential for reducing runtime by …
